To all whom it may concern: c

Be it knownthat1,.NATHANIEL YATES,

Jr., a citizen of the United-States of Amen,

ica, and a resident of Augusta, in the county of Bracken and State ofKentucky, have invented a new and'useful Improvement in a Turnb'utton Fastener, of which the following is a specification. u

My invention relates to a fastener or turn button of the kind commonlyused for fastening the curtains of vehicles. The invent-ion consists ofvarious novel featuresv are the similarly functioning elements indevices known to me up to this time.

Another object of my invention is to provide means to be employed with adevice of this kind adapted to positively secure the part thereof inpositions for the releasing therefrom or mounting'thereon of a curtain.These and other objects are attained by the means described herein anddisclosed in the accompanying drawings, in which Fig. 1 is a fragmentalside elevation of an automobile having mounted upon it curtain fastenersembodying my invention.

Fig. 2 is a sectional view through one of the fasteners embodying myinvention.

Fig. 3 is a top view of a base forming a detail of my invention. I

Fig. 4C is a perspective view of a shell forming a detail of myinvention.

Fig. 5 is an enlarged sectional view on line 55 of Fig.2. I

The fastener A comprises a base a from which extend the slotted flangesa through which screws 0. extendv to mount the fastener on a vehiclebody. The body portion or shank a extending fromthe base is oval incross section and has a top a centrally through which top is formed abore or perforation a. The top of the base has formed in it the radialdepressions a, a a and a", of which the depressions a and a extend in asubstantially straight line disposed at substantially right angles'tothe substantially straight line in which the. depressions a and aextend. A cap a having a shape substantially ovalin cross section has acentral bore a in its topa", and about'the bore is formed a depressedportion a from the perforation therethrough, ridges 1 adaptedtozacconnnodate a head a 'of a'pin I (0 The-bores in the tops ofthe capand of tliebase are insubstantial alignment, and. the pin a-.extends;through.said .perfora t-ions.'-:A shell a havin an oval'to a 723 p 7 has a circumferential flange fa extending from said top a.

The top has formed in it upwardly struck ridges a ,0 and r a, which areadapted to seat in the'depressions a, a a anda formed in the-top of thebase. The shell has a central bore (1 through which the pin a extends. A

spiral spring a is coiled about the pin and abuts the shell and" theinner surfacefof the top of the cap. The pin has an axialbore a? in itsone end, and'the material at this end of the portion of the pin isturnedor spread outwardly in any suitable manner,-

Whereby the pin is precluded from separating from the base. The flange aformed 'on the shell-extends into the cavity in the cap. The sides ofthe cap are slightly flatv and are depressed, as shown at a. The

inner walls of the depressed portions of the" cap serve to limit themovement of the shell into the cap. Any of the ridges 'on the vshell areadapted to seat in any of the .dG-

pressions in the top of the base, therefore the cap may be rotated aboutthe pin and may be retained in positions either transversely to or inlongitudinal alignment with the base. The spring a yieldingly resists Jmovement of the cap and shell on the base. The depressed portion a ofthe cap and the'head of the pin preclude entry of foreign matter intothe cap. The shell a also precludes the entry of foreign matter into thecap.

What I claim is:

v 1. In a fastener of the class describedthe combination of a base, acap and ashell of oval shape having aligned perforations, the basehaving depressions in its top radiating gaging the base about theperforation therein and a spring mounted on the pin and abutting the capand the shell.

2., In a fastener ofthe class described the combination of abase havinga slotted top, a cap having a shank and an oval top, the top of the caphaving a central slot and a depression formed about said slot, the slotbeing in alignment with the slot in the base, a pin extending throughthe slots revolubly mounting the cap on the base and having a headadapted to seat in the depression in v the cap, and forming a closurefor the per- 'foration in the cap, the pin also having formed in it anaxial bore disposed in that portion thereof adjacent the base, said lastmentioned portion of the pin being turned outward upon itself to form abead engaging the base about the perforation therein, a shell mountedrevolubly on the pin .en-

gaging'the cap and adapted to revolve therewith, a spring containedwithin the cap abutting the hell and the cap, the shell and base havingcooperating ridges and notches adapted, in cooperation with thespring,'to

yieldingly resist relative movement of the base and plate. 3 Intestimony whereof,
